LID AND SUPPORTING FRAME-WORK FOR ICE-CANS.

SPECIFICATION forming part of Letters Patent No. 467,406, dated January19, 1892.

Application filed August 19, 1891. Serial No. 403,111. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. GLOVER, of the city of St. Louis,'in theState of Missouri, have invented certain new and useful Improvements inLids and Supporting Frame- \Vork for Ice-Cans, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention relates to improvements in lids and supporting frame-workfor ice-cans, or cans used in the manufacture of ice; and 1t consists inthe novel arrangement and combination of parts, as will be more fullyhereinafter described, and designated in the claims.

In the drawings, Figure 1 is a top plan view of my improved ice-can lidand its supporting framework. Fig. 2 is a vertical longitudinal sectionof said lid, the ice-can, a portion of the supporting frame-Work, themetallic posts which support said frame-work, and the Woodenbottomonwhich saidcan isadapted to be placed. Fig. 3 is a bottom plan view ofthe lid. Fig. 4 is a detailview of a sheet-iron plate out of which mylid is constructed, or, in other words, the complete lid is composed ofcast-iron top plate, a sheetiron bottom plate, as illustrated in Fig. 4,and a layer of non-heat-conducting material interposed be tween thesame, as illustrated in Fig. 2; and Fig. 5 is a transverse section ofthe modification of the lid.

The object of my invention is to construct an ice-can lid through whichonly a small quantity of heat can pass and also construct an adjustableframe-work for supporting the series of ice-cans, and more especiallythe icecan lids. It may be noted in this connection that my invention isespecially confined to the above object, and in addition to a woodensurface on which the bottoms of the ice-cans may rest, so that the samemay not come in contact with the metallic bottom of the exterior tank,in which the series of ice-cans are suspended.

Referring to the drawings, I will first proceed to describe theconstruction of the framework which supports the ice-can lids.

. 1 indicates joists, which pass completely across the exterior tank,(which is not illustrated,) in which thefreezingmediumis placed. Saidjoists 1 are parallel to each other. Lo-

cated under joists l are cross-timbers 2, which are also parallel toeach other and pass transversely across the exterior tank. Said joists 1and cross-timbers 2 answer as a support for the ice-can lid 3, asillustrated in Figs. 1 and 2. It may be noted in this connection thatany suitable number of joists 1 may be used and placed at equal andpredetermined distances apart in the exterior tank, and also that anynumber of cross-pieces 2 may be used and placed in said tank, thusforming a series of openings between their points of intersection, inwhich the freezing-can at may be suspended.

Although I have shown in the drawings only one ice-can and one openingbetween the joists 1 and cross-pieces 2 for suspending the same, I mayextendthe construction to accommodate a series of ice-cans. The joists 1and cross-pieces 2 are mortised into each other at their points ofintersection, so that their upper surfaces are flush with each other andrigidly secured together in any suitable and mechanical manner.

The ice-can 4 is placed on a wooden bottom or support 5. Said support 5is placed on and supported by the metallic bottom 6 of the exteriortank. By this construction the bottom of the ice-can 4 cannot come incontact with the metallic bottom 6 of the exterior tank, andconsequently is not subjected to any abrasion, which would necessarilywear a hole in the bottom of the ice-can. It may be noted in thisconnection that the metallic bottom 6 of the exterior tank may besupported by any suitable foundation construction.

7 indicates cross-timbers, which are placed on the wooden bottom 5 andextend throughout the entire length of the exterior tank. Said timbers 7run parallel to the joists 1,and also parallel to each other. Locatedunder the timbers 2 and supported on the timbers 7 are metallic posts 8,which are used for supporting the said cross-timbers 2, joists 1 andalso the lid 3 of the ice-can, as illustrated in Fig. 2, wherein thesupporting-posts 8 are shown as being placed under the cross-timbers 2,directly beneath the intersection of said cross-pieces 2 and the joists1.

In place of locating the supporting-posts 8 as above described I mayplace the same under the joists 1, intermediately of the crosstimbers 2,as illustrated in Fig. 1 by circles 9. The supporting-posts 8 areprovided at their lower extremities with basic portions 10 and at theirupper extremities with screwthreaded terminals 11, on which angular nuts12 may be screwed. Mounted on said supporting-posts 8 are washers 13,which are interposed between the cross-timbers 2 and the angular nuts12. Said washers 13 are provided with projections 14, which are embeddedinto cross-timbers 2 and prevent said washers from rotating on thesupportingposts 8. From this construction it can be readily perceivedthat the supporting framework for the ice-can lid 3 may be elevated orlowered by the proper operation of the angular nuts 12.

Having given a description of the supporting frame-work for the ice-canlid, I will now proceed to describe the construction of said lids indetail, and also the construction of the ice-can.

The ice-can 4 may be constructed of any suitable material and of anysuitable form for the freezing of ice therein. Said ice-cans 4 aresuspended in the openings formed between the joists 1 and cross-timbers2 and are placed or located upon the wooden bottom 5.

I will now proceed to describe in detail the construction of the ice-canlid 3. 3 has a cast-iron plate 15, which is provided on its uppersurface with a depression 16, and located therein and secured to saidcastiron plate is a'pin 17, thus forming an eye in which a hook maybeinserted for manipulating the lid. Said cast-iron plate 15 is providedon its lower surface with a peripheral flange 18, and cast integrallywith said peripheral flange 18 and the bottom of said cast-iron plateare lugs 19 and 20. Said lugs or projections 19 are provided withrecesses 21, which converge in passing from the castiron plate 15, or,in other words, they outwardly converge and inwardly diverge. The lugsor projections 20 are provided with right-angular recesses 22, whichoutwardly converge or inwardly diverge. The bottom plate 23 of said lidconsists of a sheet-iron piece of metal, as illustrated in Fig. 4. Saidsheet-iron piece 23 is provided at its corners with V-shaped recesses 24and also with a series of smallprojections 25. Said recesses 24 andprojections 25 are formed in the sheet-iron piece of metal 23 by anysuit able machinery adapted for that purpose. When the recesses 24'areformed in said piece of metal, side flanges 26 and end flanges 27 areformed. Said sheet-iron bottom '23 is secured to the cast-iron plate 15in the following-described manner: Sheet-iron piece 23 is first formedby any suitable machinery so as to embody a form as illustrated in Fig.4. The operator or manufacturer should then bend the end flanges 27 andalso the side flanges 26 at an obtuse angle, as illustrated in Fig. 2.It is then only necessary to insert Said lid said flanges 2G and 27 inthe recesses 21 and 22, formed in lugs 19 and 20. The cast-iron plate 15is provided with a right-angular recess 28, which is adapted to fit overthe corner of the supporting frame-work piece, as illustrated in 'Fig.2. Interposed between the cast-iron plate 15 and the sheet-iron plate 22is a non-heat-conducting material 29, which may consist of mineral wool,asbestus, or any other substance which precludes heat.

In Fig. 5 I show a modification of the lid, in which I show a cast-ironplate 30, provided with flanges 31, said flanges being provided withtongues 32. The bottom of said lid is composed of a wooden plate 33, thesame being provided with grooves 34, in which the tongues 32 are adaptedto slip. Interposed between said cast-iron plate 30 and wooden plates 32is a non-.heat-conductin g material 35.
